The archived documents for the Arts Council of England’s annual report for 1965/66 includes a brief report from the SPNM accounting for its activities, which closes with the sentence:

‘In addition to these activities, a contribution of £250 was also made towards first performances of new works by young composers at the Wardour Castle Summer School of Music.’ (ACGB/51/265, ACGB/50/1310; see 1)

‘Those who heard Tragoedia when it was first performed at the 1965 Wardour Castle Summer School have said they will never forget the excitement it generated. With it his career was assured. (Hall, Michael (1984), Harrison Birtwistle (London: Robson Books), 32)

‘the first performance of […] Tragoedia […] caused a tremendous stir of excitement’ (Seabrook, Mike (1994), Max: The Life and Music of Peter Maxwell Davies (London: Victor Gollancz), 93.)

‘Actually, it was a knockout – as that evening’s rave reception of the first performance duly confirmed. And it marked the definitive arrival of Harrison Birtwistle.’ 1

‘The short instrumental first part, Eram Quasi Agnus, was commissioned by the English Bach Festival and was not composed until later ­– it received its first performance in 1969. But the bigger vocal and choral second half was performed on this occasion at Wardour Castle by the Summer School Choir with the Melos Ensemble, and soloists Bethany Beardslee, Pauline Stevens, Ian Partridge and Geoffrey Shaw.’ (Seabrook, Mike (1994), Max: The Life and Music of Peter Maxwell Davies (London: Victor Gollancz), 93.)

David Bedford: Dream of the Seven Lost Stars ‘summer school choir under John Alldis’ 1 performed on the last night (21st?) with ‘music by Messiaen and a Bach cantata’. 2, ACGB/51/1265

‘Concerts, open to the public, but free to all students, will be given during the course by the Melos Ensemble and other artists. These will include the first performances of works by Birtwistle, Goehr and Maxwell Davies commissioned for the occasion by the Melos Ensemble. The concerts will also include The Musical Offering by J. S. Bach and a performance with Bethany Beardslee, of “Pierrot Lumaire” by Schoeberg. The Summer School is also commissioning other works for these concerts by composers who will be present at the course.’ ACGB/51/1265
